Coronary Heart Disease is a disease in which plaque builds up inside the coronary arteries – which supply oxygen-rich blood to the heart muscle - over many years, leading to atherosclerosis. After a long time of build-up, plaque can harden, narrowing the coronary arteries and reducing blood flow to the heart. It can also rupture, which can result in blood clots. This can lead to a blockage in the coronary artery, also preventing blood flow to the heart. Should this occur, the risk of angina or heart attack is dramatically increased.
